Abstract

(57) [Summary] [Purpose] In the decorative formwork, only the cosmetic part on the surface is F
Made of RP. [Structure] In a mold 16 having a decorative portion 14 on its surface, a decorative mold 10 having the decorative portion 14 formed on its surface is manufactured by FRP, and a concave portion 18 is formed on the back surface of this decorative mold 10. Then, the concave portion 18 is fitted to the front surface and the side surface of the mold 16.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a decorative formwork used when constructing a concrete structure.

[0002]

[Prior Art]

 In recent years, concrete structures have been devised so that the surface of them has a stone pattern or the like to make it as natural as possible. For this purpose, it is necessary to apply the patterns to the formwork, but it is practically impossible to attach these patterns to the conventional wooden or steel formwork itself. Therefore, we used a method of making a decorative form using rubber or foam polystyrene that allows these patterns to be molded, and attaching this decorative form to the form.

[0003]

[Problems to be solved by the device]

 However, rubber softens due to the heat of hydration when concrete hardens, and can only be used several times. In addition, since the one made of rubber is heavy, it is not welcomed on site. Foamed polystyrene, on the other hand, has the advantage of being light, but its strength is weak and can only be used once. Furthermore, used materials become waste materials and cause pollution. In addition, although there is one in which the mold part is integrally molded with the FRP having high strength, there is a drawback that the price becomes high because the entire mold is manufactured by the FRP. The present invention solves such a problem, in which only the decorative portion is made of FRP and the structure for attaching the same to the mold is devised.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides, in a formwork having a decorative part on the surface thereof, a decorative formwork having the decorative part formed on the surface thereof is manufactured by FRP, and the decorative formwork is Provided is a decorative formwork which is adhered to the surface of the formwork.

Further, according to the present invention, in a mold having a decorative part on the surface, a decorative mold having the decorative part formed on the surface is manufactured by FRP, and a recess is formed on the back surface of the decorative mold. There is also provided a decorative formwork which is formed by fitting the recesses to the front surface and the side surface of the formwork.

[0006]

[Action]

 By adopting the first means, it is possible to replace only the part of the surface of a conventional product form (hereinafter referred to as the form) with a strong FRP makeup form, and it can be manufactured at low cost as a whole.

By adopting the second means, it is not necessary to cover the side surfaces of the formwork with the FRP decorative formwork and to perform the dimension matching of both parties. In other words, if the decorative formwork is attached only to the surface of the formwork, if the decorative formwork is smaller than the formwork, it will leak out when concrete is poured in, so the sides must be aligned. There is no need for this, though. Also, in the case where the decorative formwork is applied only to the surface of the formwork, the edges are relatively weakened and the corners are damaged, but this measure can also prevent this.

[0008]

【Example】

 FIG. 1 is a perspective view of a decorative mold according to the present invention, and FIG. 2 is a cross-sectional view of the decorative mold when it is attached to a mold. The decorative portion 14 is appropriately provided with irregularities, and is finished to the same size as the mold 16. This is adhered to the surface of the form 16 by using an adhesive, a nail or the like. If concrete is driven in using such a makeup mold 10 and dismantled, a makeup having irregularities opposite to that of the makeup section 14 can be formed on the surface of the concrete structure. If the decorative form 10 is removed from the form 16, the form 16 can be used as a normal form.

FIG. 3 is a cross-sectional view of another makeup mold 10 according to the present invention, and FIG. 4 is a cross-sectional view of the makeup mold 10 fitted to the mold 16. The decorative portion 14 is formed in the same manner as described above, but is different in that a concave portion 18 is formed on the back surface of the base portion 12 leaving a slight edge portion. Then, the concave portion 18 is fitted so as to cover the front surface and the side surface of the frame 16. The depth of the recess 18 is set to be approximately the same as the thickness of the mold 16 so that the back surfaces are aligned when fitted. Further, the decorative mold 10 is fixed to the mold 16 by the same method as described above.

FIG. 5 is a cross-sectional view showing another embodiment in which the decorative formwork 10 is fitted to the formwork 16. A backwood 20 of the formwork 16 is provided with a parquet 20 for improving strength. In this example, when the decorative formwork 10 is fitted into the formwork 16, the outermost surface of the recessed part 18 and the supportwork 20 of this case is displaced. It is designed to match the outer surfaces. This is done for the purpose of improving workability and strength when connecting the decorative frame 10 vertically and horizontally.

FIG. 6 is a cross-sectional view showing another embodiment of the decorative form 10, in which the wall thickness of the base portion 12 is changed according to the wall thickness of the makeup portion 14, and It is designed to have a substantially constant wall thickness. In other words, if there are irregularities on the front surface, the back surface should also have irregularities corresponding to this. By doing so, the decorative formwork 10 has the advantages of lighter weight and lower manufacturing costs.

[0012]

[Effect of the device]

 As described above, since the present invention is the one described above, the following effects can be expected. a) Since the decorative formwork is made of strong FRP, it can withstand repeated use. Moreover, since only the decorative part on the surface needs to be manufactured by FRP, the material cost is low and the weight is reduced. b) If a concave portion is formed on the back surface of the decorative formwork and is fitted into the formwork, the size of the formwork is not required and the cost can be reduced accordingly. In addition, if the inner diameter of the recess is made slightly larger than the size of the mold, fitting can be performed without any problem even if there is a slight error. c) The recessed portion reinforces the corner portion of the decorative formwork, and it is less likely that this portion will be damaged and chipped.
